WATER-CLOSET.

Specification of Letters Patent.

Patented Mar. 25, 1919.

Application filed January 29, 1919. Serial No. 273,768.

To all whom it may concern:

Be it known that I, JAMEs W. KELLY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Water-Closets, of which thefollowing is a specification.

My invention relates to an improvement in the class of water-closetequipments in which the bowl is automatically flushed with water from apressure flush-tank, the valved supply to which and to the bowl iscontrolled by the closet-seat.

The primary object of my invention is to adapt one valve-device ofspecial construction to normally shut off the water-supply to the tankand open the discharge from the tank to the bowl by raising thecloset-seat and to open the supply to the tank and shut offcommunication between the latter and the bowl by depressing the'seat.

In the accompanying drawing, Figure 1 is a view in elevation, partlybroken and sectional, of a water-closet provided with my improvement;Fig. 2 is an enlarged broken sectional view showing the springpressedvalve-stem and other details, and Fig. 3 is a similar view showing thevalvedevice.

The bowl 4 with its trapped soil-pipe 5 is of any desired form andconstruction, though where my improvement is employed for renderingfrost-proof such water-closet equipments as are designed to be locatedin places unprotected against freezing temperature, for which purpose itis especially useful, the bowl should be of iron and suitably enameled,with the lead-pipe 6' for the flushing water screwing into the flush-rim7.

The seat 8, shown hinged to the pipe 6, carries behind the hinge aweight 9 tending to hold it in and restore it' to the normally raisedillustrated position. The outer end of the pipe 6 is coupled to a closedhead 10 on the upper end of the so-called drypipe 11, through which andthe head extends a valve-stem 12 tending to be pressed downwardly by theforce of a spring 13 coiled about it, the stem carrying a disk 14: onits projecting end to extend in the path of the weight 9 and beencountered thereby, in depressing the seat, to raise the valvestemagainst the resistance of the sprin for the purpose hereinafterexplained.

coupling 15 on the lower end of the pipe 11 connects therewith adrain-pipe 1 l ading ally from the coupling and rising to an overheadflush-tank 19, which should be sealed or covered, both to cause theinflow of water to compress the air in it for increasing thedischarging-force and to prevent overflow in filling the tank.

In the coupling 15 is housed my improved valve-device 20 on the lowerend of the stem 12, and comprisinga suitably packed upper piston-valve20 and a similarly packed seating-valve 20". The valve 20 seats downwardly, under the normally-exerted expan sion-force of the spring 13,against a seat above the pipe 17 in the coupling 15, to shut off thewater-supply to the tank. By raising the stem, the valve 20 is withdrawnfrom its seat to open the supply of flushwater to the tank, and thevalve 20. is raised, to fit, piston-like, in a neck 15 of the coupling,where it shuts off communication of the pipe 18 with the pipe 11 andalso with the drain-pipe 16.

As will be understood from the foregoing description, when the seat isdepressed, the stem is raised to lift the valve 20 off its seat and thevalve 20 into the neck 15*, thereby, during the occupancy, permittingthe tank to be filled and thereafter, by the rise of the seat, shuttingoff the supply to the tank and permitting its contents to discharge intothe bowl through the flush-rim and any remnant of water in the pipe 11to drain ofi through the pipe 16 and thus pre vent freezing thereof incold weather.

I realize that considerable variation is possible in the details ofconstruction herein shown and described, and I do not intend byillustrating a single specific or preferred embodiment of my inventionto be limited thereto, it being my intention in the following claims toclaim protection for all the novelty there may be in my invention asfully as the state of the art will permit.

I claim 1. In a water-closet equipment having a bowl provided with adischarge-pipe, a flush-tank and a pipe leading therefrom, awater-supply pipe, and a dry-pipe leading to the bowl, a singlevalve-device at the junction of said three last named pipes, comprisinga valve normally seating against the pressure in said supply-pipe and ap1stona valve operating by unseating said valve to shut 'oflfcommunication between the pipe leading from the tank'and the drypipe. 2.In a Water-closet equipment, in C0111b1- nation ith the bowl andflush-tank, a
